4,4′-Dichlorodiphenylsulfone-3,3′-disulfonic acid (disodium) salt and 4,4′-difluorodiphenylsulfone were used as sulfonated monomer. 4,4′-Fluorophenyl sulfones were used as the nonsulfonated monomer. 4,4′-Dihydroxy diphenyl ether or 4,4′-thiodibenzenethiol was used as the comonomer. The sulfonated poly (aryl ether sulfone) (SPES) and sulfonated poly (arylene thioether sulfone) (SPTES) with sulfonation degree of 30% and 50% were successfully prepared by nucleophilic polycondensation. Two kinds of aromatic polymer proton exchange membranes were prepared by using sulfonated poly phthalazinone ether ketone (SPPEK) material and fluidization method. The performance of the prepared aromatic polymer proton exchange membrane was researched by the micromorphology, ion exchange capacity, water absorption and swelling rate, oxidation stability, tensile properties, and proton conductivity. Experimental results show that there is no agglomeration in the prepared aromatic polymer proton exchange membrane. The ion exchange capacity is 0.76–1.15 mmol/g. The water absorption and swelling rate increase with the increase of sulfonation degree. The sulfonated poly (aryl ether sulfone) membrane shows better oxidation stability than sulfonated poly (aryl sulfide sulfone). They have good mechanical stability. The prepared aromatic polymer proton exchange membrane with low sulfonation degree has good performance, which can be widely used in portable power equipment, electric vehicles, fixed power stations, and other new energy fields.

低磺化度芳族聚合物质子交换膜的制备及应用

使用4,4'-二氯二苯砜-3,3'-二磺酸(二钠)盐和4,4'-二氟二苯砜作为磺化单体。4,4'-氟苯基砜用作未磺化单体。使用4,4'-二羟基二苯醚或4,4'-硫代二苯硫醇作为共聚单体。通过亲核缩聚反应成功制备了磺化度分别为30%和50%的磺化聚芳醚砜(SPES)和聚亚芳基硫醚砜(SPTES)。利用磺化聚酞嗪酮醚酮(SPPEK)材料和流化法制备了两种芳香族聚合物质子交换膜。通过微观形貌,离子交换容量,吸水溶胀率,氧化稳定性等研究了制备的芳香族聚合物质子交换膜的性能。拉伸性能和质子传导性。实验结果表明,所制得的芳族聚合物质子交换膜不发生团聚。离子交换容量为0.76-1.15 mmol / g。吸水率和溶胀率随磺化度的增加而增加。磺化的聚(芳基醚砜)膜比磺化的聚(芳基硫醚砜)具有更好的氧化稳定性。它们具有良好的机械稳定性。制备的磺化度低的芳族聚合物质子交换膜性能良好,可广泛应用于便携式动力设备,电动汽车,固定电站等新能源领域。离子交换容量为0.76-1.15 mmol / g。吸水率和溶胀率随磺化度的增加而增加。磺化的聚(芳基醚砜)膜比磺化的聚(芳基硫醚砜)具有更好的氧化稳定性。它们具有良好的机械稳定性。制备的磺化度低的芳族聚合物质子交换膜性能良好,可广泛应用于便携式动力设备,电动汽车,固定电站等新能源领域。离子交换容量为0.76-1.15 mmol / g。吸水率和溶胀率随磺化度的增加而增加。磺化的聚(芳基醚砜)膜比磺化的聚(芳基硫醚砜)具有更好的氧化稳定性。它们具有良好的机械稳定性。制备的磺化度低的芳族聚合物质子交换膜性能良好,可广泛应用于便携式动力设备,电动汽车,固定电站等新能源领域。
